Breeder:

Indescribable

Mark Stanley's Swift Temper, who upset Seventh Street last month in the Ruffian Handicap (gr. I), will make her first start on a synthetic surface in more than three years as she preps for the Breeders' Cup in the $500,000 Juddmonte Spinster (gr. I) Oct. 11 at Keeneland.

With champion jockey Garrett Gomez aboard, Indescribable moved into contention approaching the final turn, put the challenge to pacesetter Whirlie Bertie, and drew off in mid-stretch to win the Kentucky Cup Distaff (gr. III) by 3-1/2 lengths.

Two grade III stakes to be contested on Polytrack -- the $150,000 Arlington Matron and the $100,000 Hanshin Cup -- join with a pair of top-notch grass events to provide a quality afternoon of racing at Arlington Park on May 23.
